This is a bit of a problem with them showing a % to hit in general, while there technically is always a % chance to roll a number high enough to hit, the actual chance to hit is all completely random. You could have a 1% chance to hit and get stupid lucky and roll a 20, or the % to hit could say you have a 99% chance to hit and then you miss 3 times in a row because you got bad rolls. It's all completely random and showing a % chance to hit makes it feel like you should be hitting more often, all you can really do is stack the deck in your favor by getting advantage from high ground or other skills and hoping lady luck is with you.
I have no qualms with the % hit chance, and I am aware that it basically translates into a dice roll. But that 25 point swing in the hit chance in my example translateys to a +/- 5 modifier to the dice roll. +/- 1 or 2 I can relate to but 5? Sounds a bit overboard to me.
